<p>The invention relates to a jet applicator station used for coating a moving web (1) of paper or board and to a method of coating a web. The applicator station employed comprises a backing roll (2) supporting the moving web (1), a jet applicator (5) for applying the coating mix to the surface of the web (1) as a jet stream and a doctor means (6) for smoothing the applied coat. The separation of the web (1) from the surface of the backing roll (2), known in the art as bagging, that occurs during jet application is reduced by passing the web (1) onto the backing roll (2) not earlier than very close to the impact point (7) of the coat jet on the web. This goal is achieved by organizing the applicator station in a novel manner, or alternatively, using an extra guide roll for deflecting the travel direction of the web (1).</p> |
